The scenario was below:
The raw material procurement type was F, MRP type was PD, Lots size was EX.
MRP Group defined the PR Document type ' ZNB'.
The MRP parameter was NETCH 2 3 1 1 1 ( or NETCH 1 3 1 1 1 )
After MRP Run, there is no PR generated.
Then use MRP parameter NETCH 3 3 1 1 1
After MRP Run, there is Planned order generated.
when convert Planned order to PR, system feedback the message 'Number range 01 for object BANF nearly exhausted'.
(In fact, I check in SNRO, the NR was 2100000000-2199999999, and current number was 2100000467)
Click yes, the PR generated with document type 'ZNB'.
I wonder why the MRP run cannot generate PR directly? Thanks for your kindly help in advance.
