Different ILN numbers in one Whs. number

[stel_p]

Hi experts,
during WT confirmation (from external WMS system) we recived HU number. That HU should be createn in EWM (external number, SSCC 18 digits), but we recived error msg: ILN basis number 6XXXX in SSCC 6XXXX00000001 is different from the required number (8YYYY)
Message no. /SCWM/SSCC013
in SPRO: Maintain SSCC Generation for Each Warehouse Number, we already have 2 lines: for 1 Whs number few seq. with different ILN basic number.
Seq / ILN Basic /
1 / 8YYYY /
2 / 6XXXX /
the question is: how to confirm WT with different HU number range (different ILN).
Additional info: we dont have any problems with creating HU with ref. to delivery (HU can be created and to assign any number range, with any ILN) but during WT confirmation we alvays have error msg. SSCC013.

thanks for any advice.
