Hi Negi,
Here's the scenario -
Data flow: A customized project management system (call it system ABC) creates the project master (without a project number). It sends the project basic information to MDM, and MDM generate the project number by rules and send back it to ABC as well as to ECC. Generally speaking: ABC -> MDM -> ABC/ECC
Project number rule:
- parent project: AA+BB+CC+AutoID (8 digits). AA = province abbr, BB = year (if 2014, BB = 14), and CC = project type (like SJ, KF, etc)
- child project: parent project number + "-" + child project number (01, 02, 03, ...). So if there are already 4 child projects under a certain parent project (eg, SH14SJ00000007), then it should get the number as SH14SJ00000007-05.
Now I am able to generate the parent project number by field's expression calculation. But for the child project, since it needs the system to calculate the number of projects that already exists under a parent project, I am still struggling with...
Regards,
