SPROC with Outer-Apply returns too many rows

I have a complicated enough SPROC, which I modified to return a few more columns (from additional tables).

What I wanted is to have this SPROC still to return the same amount of rows and the same data, but to fill in new columns (if data exists) as well, for those rows. My modification does fill new columns, but also returns more rows (based on the values it finds those additional tables).

Here is a sample of the additional table:

Table FCB:

FCBID	InvoiceID	FCBIDCode	CBCode	IsSet	FCBJrnID
ABC1	718	abcC1	cb1	0	1234
ABC2	718	abcC2	cb1	0	1234
ABC3	718	abcC3	cb1	0	1234
DEF1	718	abcC4	cb1	0	1234
DEF2	718	abcC5	cb1	0	1234
DEF3	718	abcC6	cb1	0	1234
BBB2	334	abcC7	cb2	1	3333
AAA5	225	abcC8	cb3	0	4444

Table Invoices:

InvoiceID	ProdID	TrackNum
334	P4	T7
718	P1	T1
718	P2	T1
225	P5	T5
225	P6	T6
718	P3	T1
718	P9	T1
718	P3	T2
718	P9	T2
718	P1	T2
718	P2	T2

Table FCBAP:

FCBID	ProdID	TrackNum
ABC1	P1	T1
ABC2	P2	T1
ABC3	P3	T1
DEF1	P1	T2
DEF2	P2	T2
DEF3	P3	T2
BBB2	P4	T3

The original SPROC (the main part of it) is around the InvoiceID and ProdID, and when I did execute the original SPROC it returned me only 2 rows (the correct behaviour). I.e. Search by InvoiceID = 718

InvoiceID	ProdID
718	P1
718	P2
718	P3
718	P9

I have added the following parts to this SPROC:

Added columns into the Main Query:

[FCBI].[FCBID],
[FCBI].[FCBIDCode],
[FCBI].[CBCode],

And I added another Outer Apply part, to take data from additional tables:

OUTER APPLY
    (
        SELECT
            [FCB].[FCBID],
            [FCB].[FCBIDCode],
            [LTC].[FieldText] AS [CBCode]
        FROM [dbo].[FCB] AS [FCB]
        INNER JOIN [dbo].[GenericCodes] AS [GRC] ON [GRC].[Guid] = [FCB].[CBCode]
        CROSS APPLY [dbo].[GetTranslationTable] (@LanguageCode , [GRC].[DescriptionID]) AS [LTC]
        WHERE
            [FCB].[InvoiceID] = [MT].[InvoiceID]
            AND FCB.IsSet = 0
            AND FCB.FCBJrnID = MT.FCBJrnID
    ) AS [FCBI];

What I expect to be returned in this case:

InvoiceID	ProdID	FCBID	FCBIDCode	CBCode
718	P1	ABC1	abcC1	cb1
718	P2	ABC2	abcC2	cb1
718	P3	ABC3	abcC3	cb1
718	P9

But what I’m getting instead is:

InvoiceID	ProdID	FCBID	FCBIDCode	CBCode
718	P1	ABC1	abcC1	cb1
718	P2	ABC2	abcC2	cb1
718	P3	ABC3	abcC3	cb1
718	P1	DEF1	abcC4	cb1
718	P2	DEF2	abcC5	cb1
718	P3	DEF3	abcC6	cb1
718	P9

Answer

For whatever it worth, and in case it will be clear to anyone looking into this later, the solution was to change the OUTER APPLY block as following:

OUTER APPLY
    (
        SELECT
            [FCB].[FCBID],
            [FCB].[FCBIDCode],
            [LTC].[FieldText] AS [CBCode]
        FROM [dbo].[FCBAP] AS [FCBAP]
        INNER JOIN [dbo].[FCB] AS [FCB] ON [FCB].[FCBID] = [FCBAP].[FCBID]
        INNER JOIN [dbo].[GenericCodes] AS [GRC] ON [GRC].[Guid] = [FCB].[CBCode]
        CROSS APPLY [dbo].[GetTranslationTable] (@LanguageCode , [GRC].[DescriptionID]) AS [LTC]
        WHERE
            [FCBAP].[ProdID] = [MT].[ProdID]
            AND [FCBAP].[TrackNumb] = [MT].[TrackNum]
            [FCB].[InvoiceID] = [MT].[InvoiceID]
            AND FCB.IsSet = 0
            AND FCB.FCBJrnID = MT.FCBJrnID
    ) AS [FCBI];
