Hi Sandeep
Have you run CCR first for sales order
Transaction MD04 reads the sales order requirements from tables VBBE and VBBS check those table .
check your material master mrp3 Individualrequirement. Then it will display Sales order no inMD04 screen.
APO side
You can try resending all the Sales Orders to SCM by running Initial Supply CFM9 (report RIMODINI) for Sales Order Integration Model., monitor the queues in /SAPAPO/CQ.
Also try running /SAPAPO/SDRQCR21 and check is there any inconsistencies
Just see there are many threads for above question you can refer it . If any help required let us know
regards
Virender
