Double Loop? Exist()? some way else?

Hello,

I want  to do a matching for  two tables, aiming to create a flag. The 2 tables look like following:

Table 1:

Board Nr.

Planned Method

a1

A

a1

C

a1

D

a2

A

a2

B

a2

D

a2

F

a3

C

a3

E

Table 2:

Appointment Index

Board Nr.

Used Method

Flag

1

a1

C

1

D

A

F

2

a3

B

0

D

3

a3

C

0

4

a2

A

0

B

D

E

5

a1

A

1

C

D

6

a3

C

1

E

For each board, there are planned methods (see Table 1). However, the actually used methods in each appointment may not be as planned and each appointment must belong to one board (see Table 2). When there is at least one planned method not being used, we mark the flag as 0; when all planned methods are used, mark as 1.  Could anyone help me with this match?  Thank you in advance.

Regards, Luwen

];

join(A)

load [Appointment Index],[Board Nr.],Concat([Used Method],',') as [Used Method]

Group by

[Appointment Index],[Board Nr.];

load * Inline
