Removing DateTime value from a field of a table record using code

(0) ShareShare
ReportReport
Posted on by Bilal Haider 232

I want to remove datetime values from a field of a table using code. 

There is already some value in the datetime field. If I want to make that field empty.

Methods I have tried:

1.   RandomTable."Approval Date Time" := 0DT;

      RandomTable.Modify;

2.  CLEAR(RandomTable."Approval Date Time");

If I try code like below then it updates the field with current datetime but I am unable to clear its value using above two methods.

 

RandomTable."Approval Date Time" := CURRENTDATETIME;

RandomTable.Modify;

Any help in this regard is highly appreciable.

    Yes, this way it has worked. I was trying to change multiple records that are coming to filter like this:

    TableVariable.MODIFYALL(DateTime,0DT);

    Now I have loop over all filtered records and used:

    TableVariable.DateTime := 0DT;

    TableVariable.Modify;

    But I am still confused why it was not working for all filtered using ModifyAll because all other fields are updating correctly using ModifyAll.

    Anyways, it worked for now and thanks for your answer. I have verified that.

    The above example is also in CAL on BC 14

    Hi,

    Thanks Suresh for going beyond for helping me. I acknowledge it.

    But I am using C/AL code in background to update these fields without getting user input. But I will check my code again.

    DateTime.gif

    Tested this on BC14 and I don't see any issue. I just used the below code under update action

    "Created On" := 0DT;
    MODIFY;

    That is not possible unless there is another code which is overwriting it again. What version you are using?

    After running first code I see the same old value that is populated before by using the CURRENTDATETIME function.

    After you run the first code what value are you seeing in that field? usually on SQL side there is a default value for those fields something like 1753....
