I have requirement to use Serial Number managed products. Created ECC Serial Number (ZEWM), EWM Serial Number Profile (JEC) and created my new product in MM01 then S/4HANA CIF'd in the background. All the product specific master data was created in EWM Global Data /n/SAPAPO/MAT1 however EWM Serial Number Profile field was greyed out and I can't update EWM Serial Number profile (JEC) entry in /n/SAPAPO/MAT1 or /n/SCWM/MAT1. There is no way that I can make an entry, any idea please?
I LATER REALIZED THAT ENTIRE SAPAPO/MAT1 transaction FIELDS ARE GRAYED OUT, not only Serial Number Profile. In my use-case:
1-) There is no stock in inventory for this product yet
2-) ECC & EWM Serial Number profiles are supposed to be defined differently

- Make sure you don't lock your transaction: Check SM12 if you are locking yourself
- Make sure EWM & TM integration do not cause working an issue in the same client. SAP suggests S/4HANA 1809 FSP02 requires different client for EWM & TM as a sidecar solution.
- The below answer is not a direct answer for the above question, but it is helpful to understand overall problem with Serial Number Profile management in EWM.

Symptom
Although SAP does not recommend it, it may happen that you want to change the serial number profile of an existing material. If stock has ever existed for this material in the warehouse, the serial number profile is stored in table /SCWM/SERH, and it is no longer changeable despite any changes in the material master in ERP or in EWM.
Other Terms
/SCWM/SERH, serial number profile
Reason and Prerequisites
Serial number profile changes are not supported by EWM, manual workarounds are necessary.
Solution
- 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.
