Posted on by smore

I have seen multiple examples like:

SalesParameters::numRefSalesId()
CustParameters::numRefCustAccount()
HrmParameters::numRefJournalNum()

But how can I convert a name in the UI into x++ ?

What is the Parameter for <Tes_100 ?

What is the Parameter for <Tes_105 ?

I have the same question (0)

Hi Smore,

I have open "Label search" from VS (Dynamics 365 menu -> Find labels...). Put "Billing rule" as search criteria and marked "Match exactly" option. In this case, there is only one label. I open a context menu on label id cell and choose "Find references". It will show you the list of objects where this label is used. Sometimes a label can be used in NumberSeqModule* directly or it can be assigned to EDT. If it's EDT you just continue search references for EDT.

Go to Classes\NumberSeqModuleProject\loadModule and find the entry where label is "Billing rule" (@PSA10946).

Here it is:

datatype.parmDatatypeId(extendedTypeNum(PSAContractLineNum)); datatype.parmReferenceHelp(literalStr("@PSA10946")); datatype.parmWizardIsManual(NoYes::No); datatype.parmWizardfetchAheadQty(10); datatype.parmWizardIsChangeDownAllowed(NoYes::No); datatype.parmWizardIsChangeUpAllowed(NoYes::No); datatype.parmWizardLowest(1); datatype.parmWizardHighest(999999); datatype.parmSortField(30); datatype.addParameterType(NumberSeqParameterType::DataArea, true, false); this.create(datatype);

How were you able to determine that "Billing Rule" == PSAContractLineNum ?

Hi Smore,

There is no numRef method for this type (EDT: PSAContractLineNum). If you need it, you can create your own.

The number sequence table in parameter form builds on the information provided in NumberSeqModule* classes (in your case it's NumberSeqModuleProject), but not on the list of numRef* methods on table.

Here is a picture of the 27 ProjParamters:

Which numRef matches to the "Billing Rule" ?

It's a method, not a field, so you need to add brackets.

Hi Smore,

You probably forgot to add brackets ( ProjParameters::numRefProjBudgetId() )

When using the editor, it looks like my choice is valid:

But when I compile, I get the following error:

If ProjParameters does not have that field, then why is the IDE showing that as a valid option ?

Hi Smore,

Usually, all number sequences are linked to certain EDT. If you want to find number sequence and related method (if it exists) you need

1. Identify EDT (in case of "Project budget ID" it's ProjBudgetId)

2. Find EDT in AOT

3. Find EDT references and look for numRef* method and NumberSeqModule classes (it will help you identify function module where number sequence is used).

"How is one supposed to know that ?"

Look at label of SalesParameters table.

Anyway many things in D365FO are not easy to figure out when you do it for the first time. Having a mentor, and being good at web searches are important.
