Exception handling - Difference categories in Internal process code

Hi All,

I am trying to get an understanding on difference categories in the internal process code 'DIFF' in exception handling for picking.

I understand 'Difference to difference account' is to be used to handle inventory differences and such differences can be viewed in the difference analyzer. However i am not clear about 'Difference to source storage bin'. Does this exception code have to be used only to trigger follow-on action (such as blocking a bin in case it is not accessible) or does it have any other effects?

I have a scenario where i need to carry out overpicking during WT confirmation. The excess quantity picked should not be treated as inventory difference & therefore would it be appropriate to use an exception code with difference category 'Difference to source storage bin' without any follow-on action?

Regards,

Smitha Pai
