Hi Alaa Ismail,
As per my understanding this is not a big issue, you just create your OM object subgroup level number ranges in this table first with help of OONR trxn. code, or follow this SPRO IMG path, Go To Personnel Management>Organizational Management>Basic Settings>Maintain Number Ranges>Maintain Number ranges
1) access this table via OONR
2) then create three more entries in this table if not available:
subgroup NR int. assgnmt NR ext. assgnmt
$$$$ IN EX
01AC IN EX
01AS IN EX
01AO IN EX
Note:
1) Here "01" mean current plan version and AC or C mean Object type "C" stand for JOB and "O" stand for Orgunit and "S" stand for Positions
2) Here "IN" means internal number ranges and "EX" means external number ranges, use them as per your requirements
3) then select row and click on number range maintenance button
4) you can find below table entries selective related row and click on Number maintenance button and you will reach on below table, then click on Intervals change button.
5) Maintain table entries against every OM object level and save it, kindly make sure your number ranges never overlap each other.
Hope these steps help to resolve your issue. thanks
Regards;
Bashir
