Hi Joshita,
I consider you are a beginner.
Here is one more advice to help improve your threads play meaningful role in the community.
i.e., Give an Apt Title to your Query.
For Example:
In your Yesterday's Query namely
Mass creation of Maintenance Plan
You have queried for some Table relations.The Tile should have been something like:
Knowing Work-Center Text from GEWRK field value of MPOS table.
Similarly you've given an identical Title for Today's query also, namely
Mass creation of maintenance plan
Here, you have queried some other specific thing and the Title can be like:
Object List Items in Maintenance Plan Creation
Hope you'd agree to this and implement in your posts.
