# Define transaction

Set up the transaction information needed to generate the primary input HTML.

MID

The MID list box displays the names of all the message input descriptors in the MFS source associated with the project. If multiple MIDs are specified in the MFS source set, select a MID name from the list displayed.

LPAGE

The LPAGE list box displays the names of all the input logical page descriptors associated with the MID that is selected in the MID list box. If multiple LPAGEs are specified in the selected MID, select an LPAGE name from the list displayed.

The MID and LPAGE are used as the primary input page for the transaction. For nonconversational transactions, this input page is the only input page. For conversational transactions, this input page is the first input page.

IMS Web transactions, whether conversational or nonconversational, are started from an HTML form that is generated from the single MID/LPAGE that is selected in the Define transaction TaskGuide window. This MID/LPAGE typically contains an MFLD statement for the IMS transaction code.

For IMS conversational transactions, intermediate HTML forms are generated by combining the output fields of each MOD in the set of MFS source files parsed, and the input fields of the MID referenced by its NXT=keyword.

Language

You are shown a list of the languages that IMS Web currently supports for IMS transaction data. For these languages, IMS Web converts the data between the host platform and server platform representations. Select the language of your IMS transaction data.

Synchronization level

Choose an OTMA commit processing synchronization level from the drop-down list. The default is NONE.

Tran type

Check the appropriate box depending on whether or not your transaction is conversational.
