How to find primary key(s) for an F&O entity?

Posted on by HerrimanCoder

Normally I can figure out the (sometimes composite) primary key for an F&O entity, but so far I have had no luck finding the key for any of these entities:

ItemSpecificBillOfMaterialsHeaders

ItemSpecificBillOfMaterialsHeadersV2

ItemSpecificBillOfMaterialsHeadersV3

A sample record looks like this:

{
"dataAreaId":"xyz",
"BOMId":"BOM_00000001",
"ManufacturedItemNumber":"SM-HC9578-002A",
"ProductionSiteId":"01",
"ProductColorId":"",
"ProductConfigurationId":"",
"ProductSizeId":"",
"ProductStyleId":"",
"BOMName":"HC9578-002A",
"IsActive":"Yes",
"ApproverPersonnelNumber":"000013",
"IsApproved":"Yes",
"EngChgEngineeringBomReference":"",
"EngChgEngineeringVersion":""
}

Odata URL for above record:

/data/ItemSpecificBillOfMaterialsHeaders?$top=1

For simple GET queries I can always use $filter to get what I need; but in this case I need to do a PATCH update, and thus I need the exact primary key.

I queried the metadata thusly:

/data/$metadata

...and that brought a torrent of json data. Yes, I did find all 3 entities mentioned above, but the info it's giving me is certainly not the primary key(s). For example:

Those 2 properties SiteId and dataAreadId are the same in most records--not even close to unique.

So I have been using the trial-and-error method, such as:

/data/ItemSpecificBillOfMaterialsHeaders(dataAreaId='hoft',BOMId='HOFT-006037',ManufacturedItemNumber='344-25SW')
/data/ItemSpecificBillOfMaterialsHeaders(BOMId='HOFT-006037')
/data/ItemSpecificBillOfMaterialsHeaders(BOMId='HOFT-006037',ManufacturedItemNumber='344-25SW')

In all cases I get back this error:

<Error>

<Message>No HTTP resource was found that matches the request URI 'hfcorp-uat.sandbox.operations.dynamics.com/.../ItemSpecificBillOfMaterialsHeadersV3(dataAreaId='hoft',BOMId='HOFT-006037',ManufacturedItemNumber='344-25SW')'. No route data was found for this request.</Message>

</Error>

There must be a way in F&O to look up the primary key of an entity so that a PATCH request can be done against it. How is it done?

Did you check entity in visual studio ? Key is defined at the entity level.

What am I doing wrong with this URL, then:

/data/ItemSpecificBillOfMaterialsHeadersV2(BOMId='HOFT-006037',ManufacturedItemNumber='344-25SW',ProductionSiteId='01',ProductColorId='',ProductConfigurationId='000448',ProductSizeId='',ProductStyleId='',ProductVersionId='')

Error: No HTTP resource was found that matches the request URI...no route data was found for this request.

This URL is the basis for my URL above:

/data/ItemSpecificBillOfMaterialsHeadersV2?$filter=BOMId%20eq%20%27HOFT-006037%27

And this is the JSON returned from that URL (with $filter in it):

{

"dataAreaId":"hoft",

"BOMId":"HOFT-006037",

"ManufacturedItemNumber":"344-25SW",

"ProductionSiteId":"01",

"ProductColorId":"",

"ProductConfigurationId":"000448",

"ProductSizeId":"",

"ProductStyleId":"",

"ProductVersionId":"",

"BOMName":"344-25SW",

"IsActive":"Yes",

"ApproverPersonnelNumber":"000013",

"IsApproved":"Yes"

}

Hi,

It seems like the entity you are used is a legal entity specific so you might need to include dataAreaID key into the key list as well:

dataAreaId='usmf')

Note the lower case "d" in "dataAreaId".

Thank you - when I added dataAreaId, it worked. In case anyone from MS is watching this, there really should be a simply way, in odata, to get back the PK fields for any given entity. Would save so much trouble.

I have a similar problem like @HerrimanCoder. Did you get this to work?

Actually, OData already supports it. If you download OData metadata ([your F&O URL]/data/$metadata) and locate the entity, you'll find the key definition there:

This is normally used by tools, such as code generators, but you can look there too.
