XAI in CC&B 2.2.0 : Retrieve last BILL_DT giving the ACCT_ID

Question

Hi everyone,
I try to do a Business service to retrieve a bill date giving the account id and here are the steps :
1/ Create Service program and Application service in the same name, then add it to all_users User group
2/ Create a Business service with service name equals the one created in step 1/
and Create a Java file to set the structure of the business service response.
The problem is on the screen "business service" : on the schema tab, I get the following error message :
The root LoggedException was: Service metainfo missing for 'service program name'
I don't understand what to do?
First I wanted to create a Maintenance object then Business object : it worked to get the account information given the ACCT_ID ( 1 table : CI_ACCT ), but it didn't to get bill information ( 2 different tables : CI_ACCT and CI_BILL ), and as I needed to search for the last bill date of this account I started to look at Business service.
Do you have an idea to solve this problem please ?
Thank you !
Best regards,

Answer 1

Thanks Luckys for your answer,
I managed to retrieve the information I need using a business service and not the maintenance object anymore.
The problem was a mistake in the deployment phase.
Now I face another issue : I cannot retrieve list of values in output.
But I can retrieve single fields.
For example : I need A,B, and C, but also D1 ,D2, and D3 n times which are different values in a list ( size : n ).
By doing a system log ( system.out.println ) I get the correct information, but I don't know how to store the information in a output structure ( for the list only because I retrieve the information for A,B and C ) ?
_1) The schema I used is like :_
<schema>
<input type="group">
<accountId mapField="ACCT_ID"/>
</input>
<output type="group">
<billDt mapField="CM_BILL_DT"/>
<myList type="list" mapList="CM_MY_LIST">
<D1 mapField="CM_D1"/>
<D2 mapField="CM_D2"/>
<D3 mapField="CM_D3"/>
</myList>
</output>
</schema>
_2) And the java metadata annotation for the business service is like :_
@EntityPageMaintenance (
entity = account,
service = CMPXXXXP,
program = CIPCACCJ,
modules = {foundation},
     body = @DataElement ( contents = { @RowField (     entity = account,                                                       name = account ) , @DataField (name = CM_BILL_DT)      , @ListField (name = CM_MY_LIST)   
lists = { @List (name = CM_MY_LIST,
size = 100,
service = CMPXXXXP,
body = @DataElement ( contents = { @DataField (name = CM_D1)
, @DataField (name = CM_D2)
, @DataField (name = CM_D3)
actions = { "read" },
modules = {})
_3) I finally put the info by doing the following in the business service java class :_
targetElement.put(STRUCTURE.list_CM_MY_LIST.CM_D1, localVariableForD1);
targetElement.put(STRUCTURE.list_CM_MY_LIST.CM_D2, localVariableForD2);
targetElement.put(STRUCTURE.list_CM_MY_LIST.CM_D3, localVariableForD3);
I retrieve the info for CM_BILL_DT but I don't retrieve the output for D1, D2 and D3 which need to have n different values.
Do you know how to output a list in a XAI business service ?
