    Hi,

    Yes, as I mentioned earlier it defines the cardinality in-perspective of header table.

    Thanks Chaitanya,

    RelatedTableCardinality having 2 options "ExactlyOne" OR "ZeroOne".

    The definition of both are same and just applicable for Header Table instead of Line Table.

    It's depends on Table design.

    Is't correct ?

    Thanks!

    Hi,

    Its a part of best practice to always mention RelatedTableCardinality on a relation. Yes, it defines the relation type in-perspective of header table.

    RelatedTableCardinality is mandatory to mentioned ?

    Here RelatedTableCardinality is referred HeaderTable ?

    Please give me more shed on this.

    Thanks Chaitanya,

    If the design of table (Line) is mandatory to have more than 1 records then it should be OneMore OR always 1 record then it should be "ExactlyOne" else (Optional) ZeroMore.

    Thanks!

    Hi,

    No. As per design of SalesTable and SalesLine, we can have header(record) without any lines.

    Sorry Chaitanya,

    I wrote wrong ZeroOne intead of ZeroMore.

    It should be OneMore right?

    Please give me more shed on this.

    Thanks!

    .Hi,

    I think you might be checking property RelatedTableCardinality instead of Cardinality.Refer screen shot below.
