Conversion of material ledger data during an R/3 upgrade from 3.x to 4.0 or higher Other terms CNACT, material ledger, data conversion, actual costing/material ledger, material ledger, upgrade, conversion Reason and Prerequisites This information is relevant if you have gone into production operation with the material ledger in a release PRIOR TO 4.0A and want to install Release 4.0A (or a higher release) now. If you did not use the material ledger in Release 3.0, then this note is not relevant. You can carry out a normal R/3 upgrade and then a material ledger production startup following the upgrade. Refer to Note 194465. Solution If you want to convert the material ledger data, please make sure that you have applied the latest Hot Package or the latest versions of the specified notes. Actions to take before the upgrade to 4.0 or higher 1. Get current versions of programs ZCKML_OPEN_PO and ML_PO_CONSISTENCY_UPGRADE. You can find these programs on sapserv3 in directory ftp/general/R3server/abap/note.0081463. Use Transaction SE38 to create the appropriate program objects and insert the downloaded text files into the program code. Please also maintain the text elements. You can find the relevant texts as comment at the beginning of the program code. 2. In order to keep the data volume as small as possible for the conversion of the data from Release 3.X to 4.0 and higher , archive the following objects: a) all purchase orders (archiving object MM_EKKO) that you no longer need. b) all material ledger period records (archiving object CO_ML_ML1) before the last period of the previous year that you no longer need. You are recommended not to archive the material ledger period records as of the last period of the previous year. Refer to the documentation in the R/3 library for Release 3.0 or 3.1 (Basis Components -> System Administration -> Application Data Archiving and Reorganization -> MM Materials Management). 3. Note down the plants (valuation areas) for which the material ledger was active before the upgrade. You can determine them by calling up table CKMLV in all relevant clients using Transaction SE16. In the field MEBWI you will see whether the valuation area (plant) is productive for the material ledger.

4. When you convert the purchase order history records, all purchase

order items must have been cleared, that is, the quantities delivered and calculated must agree. In case of goods-receipt-based invoice verification, each goods receipt must have been calculated. Therefore, carry out the following steps: a) Perform an account maintenance (MR11). By this, old purchase order items are cleared automatically. b) Execute program ZCKML_OPEN_PO. It generates a list of the purchase order items that are still open. c) In order to clear the open purchase order items, post all open invoices that are actually available to you but that have not yet been posted into the system. d) If the invoices are not yet available to you, reverse a goods receipt to the effect that the quantity delivered agrees with the quantiity calculated up to now. The reversed goods receipts have to be re-posted after the release upgrade. e) Execute program ZCKML_OPEN_PO again to make sure that all purchase orderitems have been cleared. 5. Carry out the material ledger settlement (Transaction CKM4) for all materials in the relevant plants. 6. Upgrade to a higher release than 4.0B: Close all finished orders (PP production order, CO production order, process order, product cost collector). After the upgrade, you need to create new orders. ('Old' orders may be transferred. During transfer, they are not included in the material ledger quantity structure management, however, and thus are not taken into account for multi-level pricing.) System actions to take during the upgrade to 4.0 or higher During the 4.x installation the system automatically deletes the internal indicator that says that the material ledger is productive using program MLXPRA3X. This occurs for all valuation areas in all clients. For the time being, no valuation-relevant movements are possible. Actions to take after the upgrade to 4.0 or higher 1. Read the current Implementation Guide for the component Actual Costing/ Material Ledger and check the accompanying settings in Customizing. Also refer to Note 122391. 2. Do not use the material ledger production startup (Transaction CKMSTART) for plants in which movement data exist. 3. Import the current versions of program ML_PO_CONSISTENCY_UPGRADE. 4. Implement all attached notes (provided that they are not yet contained in the current Support Package), so that program SAPRCKM_CONVERT_30_40 is up-to-date.

5. Run the program SAPRCKM_CONVERT_30_40 for each client to convert the

data and to return to production operation with the Material Ledger. Do this for the valuation areas that you have previously noted. (In the course of this, refer to Note 194465.) a) Select 'Portion int. tables' (parameter P_PORT). b) Deselect P_VERB. c) Deselect 'Test run' (parameter P_TEST). When larger amounts of data are concerned, you can expect longer runtimes. To increase the performance of the program, run it for each plant separately and run several instances in parallel on several application servers. Once the program has been run, valuation-relevant movements are possible again. After the run of this program, the system also converts the existing purchase orders for the material ledger. If errors C+ 606, C+ 630 or NR 751 during the program execution, please see Note 122391. The program is restartable, i.e. you can restart it at any time after a program termination without carrying out further activities. 6. If you use a database with cost-cased optimizer (for example, Oracle), make absolutely sure that new table statistics for the optimizer are created. Otherwise, you would encounter considerable performance problems with the following processing steps. In particular, use Transaction ST04 to check whether the number of records of table MLWERE is determined correctly by the optimizer. 7. For posting key WRX, create a GR/IR clearing account with open item administration. Please note that the clearing account used with active material ledger in Release 3.x (posting key WRY) did not permit open item management at purchase order item level. 8. Execute program ML_PO_CONSISTENCY_UPGRADE. It corrects the purchase order history in local and parallel currencies and thus adjusts them to the GR/IR clearing logic used in the standard system (and now in the material ledger as well). Please note that you have to execute this program twice: once each for purchase order items without and with goods-receipt-based invoice verification respectively (parameter P_WEBRE is not set or set, respectively). In particular, the run with goods-receipt-based invoice verification will have a long runtime. Please run the program as follows: a) Select option R_WERKS: enter the plants you set to productive. b) Select options R_EBELN and R_EBELP: leave these empty. c) Parameter P_DATUM: enter the date at which currency translations are carrid out that may be pending. If this field is empty, the current date is used for the translation. d) Parameter P_EKBE: should always be set e) Parameter P_DISTR: should always be set

f) Parameter P_WEBRE: set during the first program run, but not during

the second one. g) Parameter P_TEST: not set 9. If required, change the settlement control of the materials. With the conversion program, the system automatically changes materials with settlement control 1 to materials with settlement control 2, since settlement control 1 is dropped as of Release 4.0A. You can use Transaction CKMM to change the settlement control and, if required, the price control of such materials. 10. Re-post any goods receipts you have reversed before the upgrade. 11. Upgrade to higher releases than 4.0B. Create new production orders (see 'Actions to take before the upgrade to 4.0 or higher'). During creation, they are automatically included in the quantity structure management and taken into account for multi-level pricing. Upgrade to higher releases than 4.5B. As of Release 4.6B, there is an order history for production orders (PP production orders, CO production orders, process orders, and product cost collectors). This does not require any special actions after the upgrade. In particular, orders that were created and posted to before the release changeover can still be used. If problems occur during the upgrade, please contact the Development Support of SAP. At the same time, implement Note 364368. You can find further information regarding the new functions in the current documentation under Controlling Actual Costing/Material Ledger.
