Getting a SUM from another related table

[Hiperf]

Thank you in advance.

I have a tabular report that I am trying to get the grand total from a related table. This is a one-to-many relationship. There are multiple records in tblB_Summary that match one record in tblProperty based on PropertyID.

tblB_Summary has a field called XBSRent that I need to get the total of all of the rents for the Property and display it in my tabular report

tblProperty
PropertID         PropertyName              TotalRent
1234                    Williamson Towers      $5000      <-SUM of XBSRent

tblB_Summary
XBSPropertyID           Unit#       XBSRent
1234                                  Unit 1      $1000
1234                                  Unit 2      $1000
1234                                  Unit 3      $1000
1234                                  Unit 4      $1000
1234                                  Unit 5      $1000

Hello @Hiperf,

You may add the Calculated Field on the Tabular Report and use the following statement:

 SELECT SUM(XBSRent) FROM tblB_Summary WHERE XBSPropertyID = target.[@field:PropertID]

Please replace the names of the fields and the name of the table if needed. 

If all the values in the 'XBSRent' field are blank for some property or there are no records for that property in the 'tblB_Summary' table, this SELECT statement returns NULL(blank value).

If this scenario is possible and you need to display 0 (zero), the statement can be the following:
 

ISNULL(( SELECT SUM(XBSRent) FROM tblB_Summary WHERE XBSPropertyID = target.[@field:PropertID]), 0)

Thanks yet again Coopper!

It worked PERFECTLY.
