writeToDataStoreEntity vs writeToMultipleDataStoreEntities

Question

it saves when I use this: 
 a!writeToDataStoreEntity(
 dataStoreEntity: cons!AF_EXCELPIPELINE_CONS,
 valueToStore: local!pipelinetest
 ) 
 
 but does not save when I use this: 
 a!writeToMultipleDataStoreEntities(
 valuesToStore: {
 a!entityData(
 entity: cons!AF_EXCELPIPELINE_CONS,
 data: local!pipelinetest
 )
 }
 ) 
 why is that so?

The a! writeToMultipleDataStoreEntities method writes multiple CDT values to multiple entities within the same data store based on your input. Make sure your parameters are correct. 
 Here's an example of using a!MultiDataStoreEntities to store data from local variables on the click of a button. 
 a!localVariables(
 local!name: a!map(name: "D", age: 18),
 a!buttonWidget(
 label: "Submit",
 saveInto: {
 a!writeToMultipleDataStoreEntities(
 valuesToStore: a!entityData(
 entity: cons!DAF2_consProm,
 data: local!name
 )
 )
 }
 )
)

Here FK refers to foreign key

Code looks fine as far as I can tell. 
 Maybe check both your constants and make sure they are pointing to the DSE. 
 Also make sure there isn't some constraint on the database that may be preventing the insert.
