- As first step you have to remove all stock (including planned stock, which means rejection of all not yet goods receipted stock on existing inbound deliveries) for the material from the warehouse.
- Set the appropriate serial number profile for the material in ERP.
- Delete the entry from table /SCWM/SERH for the material.
- Then you can start using the material with the new serial number profile, when the new stock comes for the material the entry in /SCWM/SERH will be automatically recreated with the relevant data.
If you find it inconvenient to use debug mode to delete the entry from /SCWM/SERH you may consider using a report like the one attached to this note. It checks the physical stock for the material and if no stock found the deletion takes place. Manual check of the stock situation in the warehouse monitor is also recommended before you execute the report.
In case you intend to change the SN profile from "non-serialized" to "A" (document item level), or from "A" to "non-serialized", removing the stock is not absolutely necessary, however we recommend you to ensure that no open delivery exist using the material in question.
In all other cases removing all existing stock from the warehouse is a must.
In case you choose not to remove the stock when changing the serial number profile from "non-serialized" to "A", or from "A" to "non-serialized", you can use the attached ZSERH_UPDATE report to make the change on table /SCWM/SERH. In this case the step "Delete the entry from table /SCWM/SERH for the material." should be replaced by running report ZSERH_UPDATE instead.
Note 2354946 introduces a new delivery validation which locks the delivery in case the serial number profile stored in /SCWM/SERH does not match with the actual material master and customizing setting for the product in EWM. In this case error /SCWM/DLV_SERIAL216 is raised and the whole delivery document is locked. In order to continue the processing of the delivery, you either have to reset back your material master and customizing settings to their original state, or alternatively if the delivery item state permits it, you can decrease the quantity of the item with the affected product to zero.
