Hi when we run the above in our feeder system to flag a materials as relevant for customs the flag is set in the material master but we have no stock overview display. We also did the Distribute product data to feeder system, At this stage we should have a zero stock overview display.
We do not wish to run /SAPSLL/BWHIDP_R3 as this will transfer all stock for all plants linked with our customs ID and we only have one plant relevant for bonded warehouse.
Did I miss a step.
That control is in the CWH Authorization. Generally speaking, you would assign the Authorization to one FTO and potentially several Legal Units (Plants). In your case, you would assign only the LU for which you have Customs permission.
Unless you need the ECPID assignment for some other reason, you'd be best to unassign the Plant(s) for which you don't have Customs permission, to avoid unnecessary transactional processing in the system.
Hope that helps.
The transaction you mention is not a standard one, so I guess your team has developed it in-house. However, if you have flagged a Material to be relevant for Customs Warehousing, then you are correct in thinking that the re-distribution of the Material "Special Customs Procedures" attributes is just one of the necessary steps.
Indeed you DO need to run /SAPSLL/BWHIDP to transfer the existing stock (even if zero!), because the transfer most importantly creates a record in GTS table /SAPSLL/PRBWH, and that record activates the Product for CWH and therefore offers a stock overview. You can run the transaction just for a single Material, so no need to transfer all stocks until you are ready to do so.
By the way, the transfer is only for the flagged Materials, and only for the Plant / Storage Location combinations that have been assigned to the ECPID.
Hope that helps.
