I'm working in VFP 9.0 SP2.  I have a one-to-many program which is writting blanks fields for the many items into the one table. I have two tables:  

table "ORDERS" which holds the customer info.

table "ITEMS"  which holds the item info.

When I go to save the information I  SELECT ORDERS, find & increment the last order number and append a record with the customer data.

Then I  SELECT  ITEMS  and append the items info using this code.

IF !USED('ITEMS')
     USE ITEMS IN 0
ENDIF
SELECT ITEMS
APPEND FROM   DBF('ITEM LIST')   FOR   !EMPTY(ITEM_LIST.part_no)
SELECT 0

In the ORDERS table I am see the first row filled with the correct customer info. and I have additional rows filled with ***************** for each of the items. I was expecting to see only one row entry for each order in the ORDERS table.  It is acting like the tables are linked, but I am working with them individually.

If I have four items in an order the ORDERS table looks like this:

cust_name    |   cust_add     | cust_phone   | ......
****************|******************|*****************|........
****************|******************|*****************|  .........
****************|******************|*****************|  ..........

jws2bay, I don't know why you are not patient enough to wait for an answer to your question...

This is just a brief list of possibilities how to solve your one to may report problem.

You have several options one of them is to create the report for Ordered_items table and establish a relation from ordered_items to Customer. The report should have group band for Customer data and detail band for Ordered_items data:

SELECT 0
USE Customer ORDER TAG web_order
SELECT 0
USE Ordered_items ORDER TAG web_order

SET RELATION TO web_order INTO Customer

REPORT FORM YourReport ...

Another possibility is to create a query

SELECT * FROM Customer, Ordered_items ;
  WHERE Customer.web_order = Ordered_items.web_order ;
  INTO CURSOR ...

Above query creates two differently named columns for web_order. So, you probably should use a slightly modified report.

The view usage is similar to the query.

The last option could be e.g. Report Wizard which will allow to create the report in a minute including all relations.

Sorry Olaf, this is nothing against you and no correction to your answer. Your answer is perfect and points were assigned correctly.

My last post here was a reaction to another already deleted question...

jws2bay's speciality is to ask a question, wait one hour, and delete the question just in the time when I am working on the answer, testing it etc. I have to stop doing such mistakes...

But if the answer is already created why to put it into the trash? So, I've posted it here.

pcelba,

Sorry, I was quick on the draw.  I can understand the frustration of composing the answer and then not having the chance for it to be considered.

I had not considered putting the report together with the Customer as the group band, and the item data in the detail band. I'll have to try this out.

Thanks for the answer.

I see, haven't seen the other question at all.

I also tend to create and test samples, but lately also often keep it at pointing to the reason, often that's sufficient already.

Bye, Olaf.
