Hi
Have you: create a Customs id, have you assigned a combination of plant sloc to it in both ECC and GTS?
Have you assigned this plant/sloc to a specific IPR legal unit?
Have you assinged your products in GTS to this Customs id under IPR; have you retransfer back this info to ECC?
have you set the activity sequence for IPR accordingly ?
you need to check all the IPR settings are done.
KInd regards
Assen
