I have two transaction codes A and B for two different programs. Using T-Code B i am using MSN field and updating the Franchise Code field in that program.
But in the Transaction Code A, i am again using MSN field which is going to search for Franchise Codes. Now if T-Code B is updating her program for some MSN code and T-Code A tried to search for the Same MSN Code for franchise code, then it should give an error message that the particular MSN code is being locked by user using T-Code B.
How to lock the particular field in the program and to get the desired pop up in the other program. Please update me with the same.
