Serial number validation in sales and delivery documents

[Former Member]

Hello,

Has anyone ever had to validate that the serial numbers being entered in sales and delivery documents already exist on valid equipment master records? We are trying to find the correct place in the code (user exit) to place code to do this check without affecting any of our current manufacturing functionality. Currently a developer has added code to SAPLIPW1(?), the serial number pop-up screen which is used in many places and has caused problems in our manufacturing modules. Any guidance is greatly appreciated. Thanks.

If you can explain your sentence 'Has anyone ever had to validate that the serial numbers being entered in sales and delivery documents already exist on valid equipment master records?' in a little more detail, then perhaps I can try to find a better solution than user-exits.

Hello Kevin,

If I understood correctly, you would like to have validation check during Sales Order transaction (va01, va02) and Delivery (vl01n, vl02n) to see if the serial number is currently in the relevant stock. Unfortunately this requirement is not supported in the SAP design. The stock check works only at the moment of material movements.

When selecting serial numbers in the delivery or sales order the system will display all serial numbers that might be relevant for the sales document. If you want to have additional criteria for selecting the serial numbers you need to add them manually.

It is possible to assign a serial number with status ECUS to a sales document because otherwise it wouldn't be possible to

assign them to a return delivery.

Hope the above helps. If question answered, please close and reward points.

Hi Peter,

Thanks for your reply.

We are currently trying to find the correct place in the code to add a check to validate the serial number(s). In your opinion do you think that code could be added during document save to perform this check? Do you think such a check could also potentially cause performance problems? If you have any suggestions on which user exits to check it would be greatly appreciated.

Best Regards,

Dear Kevin,

If you wish to get detailed information on where and how to code user-exits, then the best method would be to refer to SAP Note 415716.
