Auto Generated Columns

Hi All,

We had implemented OpenClinica version 2.2.1. in our company. But, We have a difficulty in importing CDISC XML to SAS. There were no issues in creating SAS datasets, When it comes to sequence in CRF, it gives auto generated fields like "variablename_seq_A1,variablename_seq_A2...".
So the number of SAS dataset column increased. Due to this reason, the programmers feel hard to code in SAS analysis part.

In CDISC XML file there is a option for "ItemGroupRepeatKey" in tag. I hope, that will fix the auto generated column in SAS datasets.

If there are any other option to fix the auto generated fields, please let me know.

Thanks in Advance,

    Could you please elobrate more about your question? like the meaning of " When it comes to sequence in CRF, it gives auto generated fields like "variablename_seq_A1,variablename_seq_A2". If you could provide one concrete example, that could help pinpoint the problem. You see, in your CDISC ODM XML, there are 2 places specified SAS names:
    - SASDatasetName; - SASFieldName. Is your reported trouble related to one of them?

    "ItemGroupRepeatKey" is an optional attribute of . According to CDISC ODM, if , "ItemGroupRepeatKey" has to be shown in . If , "ItemGroupRepeatKey" will not be shown in . So are you saying that you have and no "itemGroupRepeatKey", and this cause you trouble?

    Thank you for your interests in OpenClinica.
