LT01/LT10 - Restrict bin to bin transfer (999 mvmt)

Dear all,

I am looking for a way to restrict the transfers from one bin to another via LT01 or LT10 via WM movement 999 on special stock.

1) Is there a way to restrict the bin to bin transfer for differnet special stocks numbers via Customizing (I am only aware of blocking the whole bin/quant)

2) Is there a dedicated User Exit to put some customized code to check the source and destination bin? Possibly an error message when pressing enter or when saving (I checked function group XLTO)

Thanks a lot in advance for your advice.

Kind regards

Karsten
