Hello Ravi Prakash,
- In standard method I would go for LSMW, which is the simplest thing. LSMW when run in Background mode takes hardly few seconds for 80 Orders.
- In an innovative method you can experiment one thing. Put a code in user-exit IWO10009 which changes the Order status from CRTD to REL (use fm 'STATUS_CHANGE_INTERN' or by updating value of CAUFVD-PHAS to '2'), when a field say Revision of Order turns to a specified value (say 'Test'). Means when we give 'Test' in Revision field of an Order (status CRTD) and Save, the Order automatically changes to REL status. If you have achieved this, then from IW38 , through Carry out mass change option when you change the 'Revision' value of a set of your 80 CRTD Orders then all these Orders should turn into REL status.
- The second one can be done by your ABAPer easily, but if you know LSMW the first one is the answer.
Good luck
