Waht is the best way to Delete records from a In Memory table since Not in is not supported in X++ query

(0) ShareShare

Posted on by Community Member

I need delete some records from VendAccruedPurchasesTmp_NA table. I tried to add filter in the Report design. But I didn't find the NOT IN operator in SSRS. So I try to delete them from VendAccruedPurchasesDP. Also NOT IN is not supported in X++ query. It seems I have to create another temp table and insert the Purchids that I need to delete. Then use notexists join to delete the records.  Is this the only way to do it. Does anyone knows any better ways?

    Thanks Nitesh.

    I'm still researching on how to use container to do it. Will keep you updated.

    If you have good examples please do share.

    Hi Martin,

    I want to filter the data from the report. what happened the data are generated due to incorrect setup on matching policy. The setup has been corrected. But the DB has unclean data from before correcting the setup.

    Hi Anna,

    The way you are thinking that also you can do, this is one of the way to implement the logic.

    I suggest you not to create temp table to implement your logic, its having overhead of creating table object in AOT.

    may be you can do following:

    create a container and have purchid in it.

    analyse  VendAccruedPurchaseDP class and find out where it inserts record in VendAccruedPurchasesTmp_NA table

    there you should have a validation and condition based on container purchid

    this logic will make you modify only the class logic

    Please verify and update us if this helps you.

    You normally use delete() method in AX to delete data from In Memory temporary tables.

    Nevertheless I'm not sure what you're trying to achieve with all those ranges, NOT IN operators and joins. You're saying that you use join to delete data, but join won't delete anything, it will merely filter data. Do you want to delete data or filter data?
