Stored procedure EcWriteEntity

helper procedure to write data into DI – mainly for bulks consisting of more than one EcENTITY row

parameter	type	direction	description
@EntName	nvarchar (100) Required	Input	Entity name – for description, see Table EcENTITY, field ‘name’
@BulkId	int Optional	InputOutput	Transfer request bulk_id – see remarks under Table EcENTITY description use NULL value to create a first EcENTITY row; the procedure creates a new bulk_id value and passes it back for writing next EcENTITY rows (within one bulk) use the value which this procedure returned in this parameter when writing the first EcENTITY row
@EnClassID	nvarchar(10) Optional	Input	Entity type if omitted, ‘ITEM’ value is used
RetValue	bigint	ReturnValue	EcENTITY.id inserted
