Hi!

1. Refer to the CRT\_DD Specs 1.0.0 (define.xml standard) Section 2.1.3.1 (p.18) table.

2. See an example from Section 2.1.2.5 (p.15):

\<CodeList OID=“CodeList.AESER”

Name=“AESER”

DataType=“text”

SASFormatName=“$AESER”\>

No

Yes

Hello Sergiy.

Thanks for your response.

I have the codelist element and its attributes in the same order as in the CRT\_DDS V1.0. Same applies to the itemgropdef and itemdef elements which are the other 2 areas where i am getting an ERROR.

Please see the layout of my define.xml file.

def:AnnotatedCRF

ItemGroupDef for all the datasets.

\<ItemGroupDef…\>\<ItemRef…\>

ItemDef for all the variables.

\<ItemDef…\>

All Complutational Algorithms are listed here.

def:ComputationMethod\</def:ComputationalMethod\>

All Codelists are listed here.

\<CodeList…\>

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* →

\<def:ValueListDef OID=“ValueList.VS.VSTESTCD”\>

\</def:ValueListDef\>

Thanks,

Nalin

Thanks, Sergiy. This table helped resolve the issue. I had the wrong order for def:ComputationalMethod & def:ValueListDef
