How to check for priorvalue of a multipicklist is blank in Validation Rule?

Question

Hi Community,

I already tried it a few times. This was probably the closest one:

ISBLANK(TEXT(Priorvalue(K_FS_MP_StatusInformation__c)))

"K_FS_MP_StatusInformation__c" is a multipicklist value

Basically I want to check if the priorvalue of this multipicklist field was empty but I am struggling to write it in the right way.

Any ideas?

Many thanks in advance!

Regards,

Benedict

Hello Benedict,   You can check like this: IF(ISBLANK(Priorvalue(K_FS_MP_StatusInformation__c)),true,false) Thanks

Hi,   Please try    So this will be true if priorvalue of that field was blank.  AND( ISCHANGED(K_FS_MP_StatusInformation__c), ISBLANK(PRIORVALUE(K_FS_MP_StatusInformation__c))
