  • What is ‘Append’ and ‘Append To’ privilege in MSCRM? Give one example of it?

‘Append’ and ‘Append To’ priviledges works together. ‘Append To’ priviledge will allow other entities to get attached with the entity. ‘Append’ priviledge will allow the entity to attach the records to the entity with ‘Append To’ privildege.

Let us understand this with simple example:
Let us say that you want to attach a note to a case then note entity should have ‘Append’ access right and case entity should have ‘Append To’ access right.

Let us take one more example to understand this. Suppose you have two custom entities called ‘TestCustomEntity1’ and ‘TestCustomEntity2’. You want to attach the ‘TestCustomeEntity2’ records to ‘TestCustomEntity1’records. For this you need to have ‘Append’ access right on ‘TestCustomEntity1’ entity and ‘Append To’ access right on ‘TestCustomEntity2’.
Now guess will I be able to attach the records? Answer is “NO” because we need to create a 1:N relationship between ‘TestCustomEntity1’ and ‘TestCustomEntity2’.
Now the user who has above mentioned access right in his security role will only be able to add ‘TestCustomEntity2’ records to ‘TestCustomEntity1’.
