How could i know, Screen field value has been changed or not In Me22N.
I am facing one problem.My Requirement is In me22N down payment field is available. Down payment amount is entering the user partially.
Means Suppose In Me21n document total is 50000.00 . First time while adding they entered 5000.00 , Renaming Balance is 45000.00.
So, i need to validate the down payment every time user save the document. I can able validate the records the problem is.
Total amount 50000.00.
1st time 5000.00
2nd time 30000.00
3rd time 15000.00
Down payment is completed, Now User is login into the Screen i did some changes in the other fields. And saving the Document.
Actual amount is 50000.00 already posted. but last 3rd time amount 15000.00 is showing in me22n. the coding part is thinking again user has entered 15000.00 for down payment. 500000+15000 > Actual amount 50000.00 Error message is triggering. But last 15000.00 Actually user has not entered. i.e Previous Transaction amount.
So, My questions is I open me22n. i did some changes in down payment. before saving the records how could i know whether the field has been changed or not. Any idea.
If your answer is compare the database value of the po in the data base. I hope this is wrong.
4000.00 I was entered and saved, Again i open the me22n this time also 4000.00 i was entered, So, Changes has done. So, i can not compare screen values to the Database values. Need valuable suggestions.
