Table Relations (Normal , Related Field Fixed , Field Fixed) in AX 2012
ClothesTable has the following fields: ClotheId, Name and CollectionTypeId
ClothesOrder has the following fields: OrderId, ClotheId, Qty OrderId could be a number sequence and Qty entered manually by the user.
0 – Men
1 – Women
2 – Children
Example 1: Related Fixed FieldOn MenClothesOrder we create a new relation to ClothesTable and specify the following two:
1. Normal = ClotheId to ClotheId (Best practice to specify this on the EDT) and
2. Related Fixed Field 0 = ClothesTable.CollecTionTypeId.
This shows that the lookup to the clothes table should show only clothes with the same ClotheId (point 1) AND clothes that are of type Men (point 2) because the table deals with order for mens\’ clothes. We use 0 because Men is element 0 in the Enum.
Lets say you have 4 tables
1. ChildernClothesTable
2. MenClothesTable
3. WomenClothesTable
4. ClothesOrdersTable
Create BaseEnum CollectionTypeId with the following elements:
0 – Men
1 – Women
2 – Children
Create Extended DataType CollectionTypeEDT of BaseEnum CollectionTypeId. Now use this EDT in your ClothesTable.
ClothesOrdersTable has the following fields:
1. ClotheId,
2. Name ,
3. CollectionTypeId and
ChildernClothesTable, MenClothesTable and WomenClothesTable has the following fields:
1. ClotheId,
2. Name
Case 1:
On ClothesOrdersTable we create a new relation to MenClothesTable and specify the follwing two relations:
1. Normal = ClotheId to ClotheId and
2. Fixed Field ClothesOrdersTable.CollecTionTypeId = 0 and SourceEDT = CollectionTypeEDT
This shows that the lookup to the MenClothesTable should show all clothes with the same ClotheId (Define in Normal Relation) AND clotheId will only bring from MenClothesTable as we are using type Men (Define in Fixed Field Relation) because we want to activate relationship for mens\’ clothes. We use 0 because Men is element 0 in the Enum.
Case 2:
On ClothesOrdersTable we create a new relation to WomenClothesTable and specify the follwing two relations:
1. Normal = ClotheId to ClotheId and
2. Fixed Field ClothesOrdersTable.CollecTionTypeId = 1 and SourceEDT = CollectionTypeEDT
This shows that the lookup to the WomenClothesTable should show all clothes with the same ClotheId (Define in Normal Relation) AND clotheId will only bring from WomenClothesTable as we are using type Women (Define in Fixed Field Relation) because we want to activate relationship for Womens\’ clothes. We use 1 because Women is element 1 in the Enum.
Case 3:
On ClothesOrdersTable we create a new relation to ChildernClothesTable and specify the follwing two relations:
1. Normal = ClotheId to ClotheId and
2. Fixed Field ClothesOrdersTable.CollecTionTypeId = 2 and SourceEDT = CollectionTypeEDT
This shows that the lookup to the ChildernClothesTable should show all clothes with the same ClotheId (Define in Normal Relation) AND clotheId will only bring from ChildernClothesTable as we are using type Childern (Define in Fixed Field Relation) because we want to activate relationship for Childern clothes. We use 2 because Childern is element 2 in the Enum.
Hope it will help you to understand Fixed field Relation in Dynamics AX………
Happy DAXing…… 🙂
