SysOperationControlVisibilityAttribute is a very useful attribute in Dynamics 365 Finance & Operations (D365FO), especially when you are designing SysOperation (aka Data Contract) forms for batch jobs or services. Let me explain it clearly:
SysOperationControlVisibilityAttribute is an X++ attribute applied to Data Contract fields.
It controls the visibility of a control (field) on the SysOperation form (the dialog generated automatically for your batch job/service).
When you use SysOperation / Service Framework, D365FO automatically generates a form for your Data Contract (the contract parameters you define).
Sometimes you want:
Certain fields to always be hidden.
Fields to be visible only when certain conditions are met.
Fields to not appear at all in the UI, even though they are in the contract.
That’s what SysOperationControlVisibilityAttribute does.
To hide a contract parameter from the UI, decorate the parameter method as follows:
[DataMemberAttribute, SysOperationControlVisibilityAttribute(false)] public int64 parmHiddenWorkItemId(int64 _workItemId = workItemId) { workItemId = _workItemId; return workItemId; }
First read the answer fully, then try to explain it in your own words. After that, open a few related questions and compare the concepts. This method helps you remember the topic for a longer time and improves exam preparation.
