Hi,

There are several poins which I can share out of my experience.

We had migrated from 4.0B to 4.7

1. You need to take care of the user-exits in programs such as MV45AFZZ.

Incase the upgradation is of earlier versions in which the modification assistant was not available then

the user-exits codes are lost as the original objects which come from SAP do not have the user

defined codes.

2. Incase you have modified any standard SAP program for your purpose then your code will be lost.

For e.g; for sales order numbering our company had a special logic to be incorporated. We could not

achieve this through user-exits. So we had modified standard SAP for this special requirment.

3. Since the unicode checks were not active in earlier versions; so in few of our programs in which we

were moving data from one string structure to another it resulted in syntax errors due to the unicode

restrictions. So had to take care of them.

4. Incase you have added your own indices on SAP tables and in the newer version SAP provides the

same index on the same table; then it will prompt you about this.

5. As in any upgrade or support patches application you need to clear the SPAU/SPDD list.

These are few issues which we had encountered. So you can keep a note of these.

Hi,

As per my experiece, point 1 and 3 above should be the most time consuming.

From which version and to which one are you upgrading?
